HACH INEFGR MECHANICALLY TELLING- THE SOIL.

Specification of Letters'Patent.

Patented Oct 28, 1913..

hpplication filed August 9, 1912. Serial No. Yldflfili.

To all whom it may concern Be it known that I, CLIiMENT Croconnvr, asubject of the King of Italy, and resident of Paris, France, (whosepost-oiiice address is 14: Rue Tronches, Paris, France,) have invented anew and useful Improvement in Machines for Mechanically Tilling theSoil, which invention is fully set forth in the following specification.

This invention relates to a machine for mechanically tilling the soil bymeans of. special tools which from their shape and the results of theirwork may be compared to.

actual spades. This machine for mechanically tilling the soil is chieflyconstructed of a frame mounted upon wheels carrying a suitableexplosion, steam, electric or other motor for driving the tools, thesaid motor also being capable of efi'ecting the traction oi the machineunless the said machine is actuated by an exterior mechanical or animalforce. The chief characteristic of this machine, outside the generalarrangement of the parts constituting the same, is the form of the toolwhich tills the soil which tool has been devised so as to give rise toas little ihriction as possible.

In the accompanying drawings: Figures l, 2 and 3 show one of the toolsin side eleration, front elevation and plan respectively. t and 5 showbyway of errlltli ample a rose or crown formed with the said radially.Fig, 6 is a modification showing another method of flirting toe toolsupon the hub, allowing of using fiat tools. Fig. l is an elevationillustrating a method of application of these tools to a machine fortilling the soil according to the invention. Fig. 8 is a plan showingthe arrangement of the tool carrying frame.

As shown in Figs. 1, 2 and 3 the tilling tool consists of a base a, aweb 5 and a spreading head 0 with a cutting'edge on the side where itenters the ground, so that trozn the lease. up to the end cl oi? thespreading head thesaid tool is -progressively and continuously twisted.The spreading head is provided with a heel e which can be more orlesstwisted toward the rear. The object of this arrangement is that whenthe tool turns toward the right hand it enters the ground with thepoint, and with its cutting edge, exerting upon the detached clod ofearth a pressure from the ironttoward the rear, whereby the advance ofthe machine I is not only unimwded but is even facilitated;

the tooltherefore enters the ground like an actual spade. The heel eserves the purpose of a diverter by completely turning over the detachedclod of earth. It will also be seen by reference to Fig. 1 that thefront end (5' describes, in the rotary movenicntof the tool, acircumference 01 larger radius than that described by the end of theheel e. in this manner the friction upon the upper edges 9 of the toolis reducedto a minimum, which is ofgreatest importance from the point ofview oi the force to be developed.

The various tools are preferably mounted radially like the spoltes of aWheel perpendicularly to a common axis so as to constitute a kind ofrose. By reason of the spreading of the tools it will be seen that themass.

speed, the live force of the tools forming a rose is added to that oithe tool enter-in the ground and serves to overcome the a normalresistances which might there he met with. 1

Figs. d and 5 by means of dislrs clamp' the base of the tools, whichdislrs are unit Joy bolts h. in l igs. l and 5 one of the disks issupposed to he removed. in Figs. 1 and 5 the tools are shown live innumber, but any other suitable number can be employed. Fig. itillustrates how a curve starting from the base a can be avoided bydirectlymounting the said tools in an inclined manner with relation tothe hub. Tn this case instead ot the required inclination of the toolwith relation to the hub arising from the curve of the tool, it simplyarises from the position of the tool with relation to the hub and thetool is fiat. It will therefore be seen that the working principle ofthe tools really consists in causing the latter to enter the ground in adirection inclined with re- The tools A can he mounted as shown in themachine. But the tool with progressive curve shown in Figs. 1, 2 and 3is preferable, generally speaking to the flat tool the web 6 of which ismounted inclined in the two plates B, B having the necessary recessesfor receiving the base of the tools.

I will now describe the complete machine as represented by way ofexample in Figs.

7 and d. This machine comprises 3 crowns or roses of tools 1, 2 and 3.These crowns of tools are keyed through the medium 0fv their disks Bupon three shafts 4, 5, 6. As shown in Fig. 8 these three crowns areplaced in three parallel planes so as to avoid interfering of the tools.The third crown 3 for example can, however, be placed in the same planeas crown 1, and only crown 2 be displaced with relation to the two othercrowns. From this point of view various combinations are possible. Onthe shafts 4, 5 and 6 are keyed toothed wheels 7, 8, 9 which receivetheir rotary movement through the chains 10, 11, 12 running over threepinions 13, 14:, 15 keyed upon the shaft 16 actuated by the motor 17through the medium of the rotatable shafts 18, 19 having two universaljoints 20, 21 the latter of which is connected to one end' of the shaft16. Moreover the tool holding frame 22 is connected to the main frame 23of the machine by a jointed parallelogram 24 which includes sleeves 25within which revolve the screws 26 operated in a suitable manner by thedriver. The tool carrying frame 22 bears upon the ground through themedium of a small carriage 27 connected to the parallelogram 24 and isprovided with rollers 28. This jointed arrangement is designed to causethe tilling tools always to work vertically and at the same depth byrendering them independent of the unevenness of the ground over whichtravel the wheels 29 which may sometimes rise and sometimes descend. Bycausing the screws 26 to turn, the displacement of the tool carryingframe 22 is caused so as to regulate the depth of work ofthe tools andto entirely lift the tools when moving the machine from one place toanother without working.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be performed, I declarethat what I claim is:

1. A revoluble cultivating implement adapted to be mounted on-a hubturning on an axle parallel to the line of advance movement of thecultivator machine, and comprising radially disposed thick and heavyblades having a predetermined pitch and very much spreading toward theirperipheries, each presenting a cutting edge terminated by a point like ahack at the periphery and a massive heel at the rear, said heelpresenting a much twisted surface merging into the surface proper ofsaid blade to form a moldboard. V

2. A revoluble cultivating implement adapted to be mounted on a hubturning on an axle parallel to the advance movement of the cultivatormachine, and comprising radially disposed thick ,and heavy blades havinga helicoid surface, a predetermined pitch and spreading very much towardtheir peripheries,.said blades each presenting a cutting edge terminatedby a point like a hack at the periphery and a massive heel at the rear,said heel presenting a much twisted surface merging into the surfaceproper of said blade to form a moldeboard.

3. A revoluble cultivating implement adapted to be mounted on a hubturning on an axle parallel to the line of advance movement of thecultivator machine, and comprising plane radially inclined thick andheavy blades having a predetermined pitch and spreading toward theirperipheries, said blades each presenting a cutting edge terminated by apoint like a hack at the periphery and a massive heel at therear, saidheel presenting a twisted surface merging into the surface proper ofsaid blade to form a moldboard.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
